Using PTP 1.8, we have created a "master" tour that links to several "secondary" tours and have added some additional buttons with custom XML for the different tours.

My question is this : when going from tour to tour, the added buttons on one tour do not clear themselves. For example, Tour A has 4 buttons and Tour B has 2 buttons. If the user is in Tour A and clicks to go to Tour B, the 4 buttons from Tour A remain and don't clear, and the Tour B buttons are present too.

Is there a line of XML code that will remove those buttons on click to the new tour?
